Definitions

  • the present invention relates to a fire curtain.
  • Such curtains are used in constructions, and especially in establishments receiving from the public, in order to avoid the spread of fires between different parts of the building. These curtains thus make it possible to compartmentalize large volumes and usually consist of a canvas limiting the spread of flames and fumes during of a fire.
  • Document FR-A-2 300 582 describes a device firebreak including features such as as set out in the preamble of claim 1.
  • Document FR-A-2 287 926 also describes a fire curtain of a structure not allowing either more to prevent the spread of the fire when a part of the curtain suspension structure collapses.
  • the object of the present invention is to resolve the disadvantages above by proposing a device forming a fire curtain including the features techniques as defined in the section Characterizing of claim 1.
  • a fire curtain 10 is attached to an upper frame 21 of a construction 20.
  • the latter can for example be a building large dimensions for industrial purposes or intended to receive a large number of people.
  • the curtain 10 comprises two integral walls 11 to each other along a lower end 11d and vertical edges 11e of the curtain 10.
  • These two walls 11 include ends 11c upper fixed to the upper frame 21 on the entire width of the curtain 10.
  • the curtain 10 thus forms a pocket attached to the upper frame 21.
  • the walls 11 are made of fabric of classes M1 or M0 limiting the spread of flames and hot or flammable gases and thermally insulate the two parts of the construction separated by the curtain 10.
  • These walls are formed as examples fabrics and glass fibers, fabrics in cotton / polyester or ceramic fiber reinforcement keep on going. These fabrics are liquid tight or allow only a small amount of liquid to ooze in the case of a cotton / polyester fabric.
  • Watering means 23 for a fluid on the curtain are provided on the upper frame 21 of the construction 20.
  • these means 22 are suitable for watering by the fluid at minus an inner face 11a of a wall 11, that is to say one of the faces 11a facing the two walls 11.
  • the fluid used in the example described below is water. Another liquid or refrigerant gas could also be used.
  • At least one of 11th vertical edges includes near the end lower 11d of the curtain 10, evacuation means 12 fluid from the sprinkler means 22.
  • a wall 26 of the construction 20, adjacent to the vertical edge 11e of the curtain 10, comprises means for fluid recovery 28.
  • the evacuation means 12 consist of an orifice arranged at a height predetermined above the lower end 11d of the curtain 10.
  • the water escaping through this orifice 12 is recovered in the recovery means 28 which can include a pumping device 28 and possibly recycling water to redistribute it to watering means 22.
  • the orifice 12 can be located at a height equal to About 250 mm above the ground 31 and the end lower 11d of curtain 10, i.e. equal to about 1 / 40th of the total height of the curtain, so that a volume of water remains trapped inside curtain 10 with double walls 11.
  • This accumulation of water in the lower part of the curtain 10 ensures the stability of the latter and good tension, as well as the sealing on the ground 31 of an area by compared to another separated by the curtain 10.
  • the sprinkler means 22 include two series nozzles 30 arranged on the upper frame 21 of the construction 20. These nozzles are suitable for watering a inner face 11a respectively of each wall 11, independently of each other.
  • the sprinkler means 22 include water supply pipes 32 fitted with nozzles uniformly distributed over the width of the curtain 10, that is to say along the upper end 11e of the curtain 10.
  • projection nozzles 30 make it possible to form a curtain of water or a blade of water over the entire area of the inner face 11a of a fabric 11.
  • This indoor irrigation with water causes water to evaporate in the event of a fire providing convective movement and cooling of the interior elements of the curtain 10, such as the irrigation system 30, 32 itself or the frame part 21 supporting the curtain.
  • the two walls 11 are connected by strips 13 forming spacers and equal length to maintain the two walls 11 parallel to each other.
  • the bands 13 can be made up of Canvas straps identical to that used for the walls 11.
  • These strips 13 can have a length between 0.5 and 1.5 meters, thus adjusting the spacing between the two walls 11. Preferably, this spacing is between 0.8 and 1 meter.
  • the bands 13 forming spacers are adapted to rupture under a tensile force of intensity substantially equal to the weight of one of the two walls 11.
  • the strips 13 have a breaking strength calculated for allow the tears 13 to be torn and the place of the other wall, on the side of the area of the construction remaining in place.
  • a rupture zone 21a is arranged in the framework 21 allowing the subsidence of one part of the construction 20 leaving the adjacent parts stable.
  • the curtain 10 according to the invention extends substantially below this rupture zone 21a.
  • the curtain 10 has several strips 13 evenly distributed over its length as shown in Figure 5 and several bands 13 superimposed on the curtain height as shown in figure 2.
  • Each strip 13 forming a spacer comprises a connecting piece 14 adapted to slide on a cable or ribbon 15, this cable or ribbon 15 having a first end 15a fixed to the lower end 11d of the curtain and a second end 15b fixed to a reel 23 secured to the upper frame 21 of the construction 20.
  • protective plates 24 are attached to the upper frame 21 and extend towards the ground 31 on a height sufficient to hide the entire curtain 10 when in position folded as shown in Figure 4A. These plates have a length equal to that of the curtain, between 80 and 100 m and a height of approximately 0.5 m.
  • This height corresponds substantially to the size of the curtain 10 folded back when the latter has a height of approximately 10 meters in the deployed position.
  • protective plates 25 are integral with the vertical walls 26 of the construction and extend parallel to the curtain 10, on each side of it.
  • a zone 27 can be delimited by the plates 25, the vertical wall 26 adjacent to an edge 11e of the curtain 10 and a second side wall 26a parallel to the first vertical wall 26 in order to accommodate the sprinkler control and recovery mechanisms the water.
  • These protective plates 24 and 25 are of preferably made of a class fire-resistant material M0.
  • the deployment of the curtain 10 is controlled either manually or automatically, following an order given for example by a fumes.
  • the reel 23 is then rotated, by a motor (not shown) for example and the cable or ribbon 15 is then progressively unwound.
  • the bands 13 slide progressively on the cable 15 so that the walls 11 unfold.
  • the curtain irrigation is then controlled either on the two interior faces 11a, or only on the face 11a of the wall exposed to fire.
  • Control means are suitable for automatically controlling the setting running irrigation nozzles 30 spraying water on this wall 11 held in place, alternating the operation of the two series of nozzles 30.
  • the curtain according to the invention therefore allows compartmentalize tall buildings volumes and thus very effectively limit the spread of fire.
